IMPRVEMENT IN WATER-WHEELS- The Schedule referred to in these LettersPatent and making parigi the same.

To all whom it may concern:

Be it known that I, BENJAMIN I. T'ALBOTT, of Iowa Falls, Hardin county,State oi' IoWahave inventedfcertain new and useful Improvements inWater- Wheels, and their appurtenances; and I do hereby declaro thatthesame are described and represented i'n the following description andaccompanying drawings,

p so as to enable any person skilled in the art to make and use thesame, without further invention or experiment.

The object of my invention and improvements is to so arrange andconstruct awater-wheel and its appurtenances, that it, with its gate,curb, andimmediate surroundings, may be made in few pieces andcornpleted and put together at the foundry, or machineshop, ready foruse, 'and be transported whole, so that when it arrives atits'destination a hole may be cut in the bottom of a box or rlume,^andthe wheel set into it, and it will then be ready for the water, whichmay be let in to turn4 the wheel.

- The nature of my invention consists in providing a cylindrical curb orcase around a water-wheel, for'its protection, having an inside flangeat the top, and an outside ilange at the bottom and in arranging acylinder within the wheel, with openings for admitting water to theWheel, the same having an outside ange by which it is supported, and abottointo support the weight of the water above; also, in ,providing acylinder, fitting in the one last mentioned, supported also by a fiangeat the top, and having openings for the water to pass throughcorresponding to those of the cylinder outside of it, 4but movable, soas to regulate the quantity of water'admitted to the wheel; and inproviding aspider-frame fastened to the outside curb or case forsupporting the step of the wheel-shaft.

In the accompanying drawings- Figure l is a perspective view of .thecylindrical curb and its flanges, with s ueh other parts as may bereadily seen. i

Figure 2 is asection of the wheel and its belongings, eut verticallythrough the centre.

Figure 3 is asection of the wheel, cylinder, and gate, below the line zz on fig. 2.`

In these 'drawings- D is a cylindrical curb, made larger than the wheelp A, so as to permit the water issuing from tile-wheel to pass downfreely betweenl it and thecurb.

`I prefer to make this curb of cast-iron, with a flange, E, on theoutside'at the top, to rest on the bottom 'of the Huma-and support thecurb when the wheel is set in its place for operation; also, with aflange, F, on the inside, to project over the top of the wheel, as shownin the drawing, to support the cylindrical ease B, fitted to the insideof the flange F and wheel A, and supported by a flange on the outside,at 4the top, resting on the flange F.

The case B extends down through the wheel A, as shown in the drawing,vand is provided with a bottom, G, to sustain the water above, so as toprevent it from pressing downward on the arms A3 ofthe wheel, andincreasing the friction in the steph a of the shaft A1.

' This shaft'passes up through a hole in the bottom G, and is held abovethe wheel by the frame H, fastened to the ilange F, as shown ink thedrawing.

The arms A3 are fastened to the lower rim of the wheel A, and to theshaft A1, which is turned by the wheel, and may be provided with apulley, or gear, or coupled toauother shaft, to turn machinery.

The m'ms A A of the wheel are connected by the buckets A, which may bemade in the form shown in g. 3,'or in such other form as may bepreferred.

The cylindric case B is provided with openings e, for

Vthe water to pass out against the buckets A2, to propel the wheel.

To close the openings c c, I make a second cylinder, O, to fit theinside of B, with openings vcorresponding to the openings c c in thecase B, as shown in g. 3, and provide it with a flange on the outside,at the top, to rest' and turn upon the top of the ease B, so that it maybe moved to open or close the openings'c c, and

thus 'regulate the quantity of water admitted to the wheel.

'loturn the cylinder G, I fit a shaft,.02, to turn in the flame H andiiange F, with a pinion, O1, on it, to take into the teeth C on. theflange of the cylinder C, as shownin iig. 1.

The bridge-tree I is fastened to the'curb D, to sup-` port the step'aofthe shaft A1 of the Wheel.

lhis wheel and all its appurtenances may be made at a. foundry ormachine-shop,and`f1tted together, and

transported, without being separated, to the place Where it is to beused p The principal advantages of ymy wheell are- First. The wheelitself is made very Wide or of great diameter, in order to givegreatleverage tothe water. acting upon the buckets; and the buckets aremade,

very shallow andwith a small issue, so as to occupy only a narrow rim atthe verge of the Wheel; and the height or length of. the buckets is verygreat in order to give them sufficient capacity for the necessary amountofwater; the inner ends of the Vbuckets are curved to iit the' outercurve of the hollow cylinder B,

while the whole face of the bucket is presented -to the direct action ofthe water-shoot,and to the constant pressure of the copious volume ofwater, settling steadily down within the cylinder B, thus preventingagitation and broken currents and consequent loss of power. Second. Thehollow-slotted cylinder B is of such4 shape as to be easily cast andnished, and not liable to strain or crack in cooling, as Would'be thecase if cast with a central small' cylinder enclosing the shaft ofthewheel;- and this cylinder,l beingboth broad vand high,

brings a full volume of water, in a state of comparative rest, to occupyabout fteen-sixteenths (HL) of the entire diameter of the wheel; andfrom this cylinder the water has to ow only an inch to strike the 4fullface of the buckets at the rim or extreme verge of the wheel; at thesame time this cylinder relieves4 l especially the hollow-slottedcylinder B with the shaft I passing through a hole in the bottom of thecylinder,

and through the water in which it revolves, so that l the whole spaceinside of the buckets isr occupied by a broad column of water in acomparative state'of rest.

Having thus fully described my invention,

1. The hollowrcylinder B, and the gate 0,'in combination with the .shaftand wheel, substantially as set forth.

2. A turbine-wheel, consisting of the wheel A, the registering interiorand exterior cylinders B and O, with the register-operating. mechanismc1 c2 c3, the projecting cover F E, and the Vshaft A', stepped upon the1spider I, all combined, arranged, and operating silbstantially as setforth.

In testimony that I claim the foregoing as my own, I affix my signature,in presence of two Witnesses.
